The central government and the General Office of the Central Committee of the Communist Party of China issued a regulation last May calling on "naked officials" to draw up reports about their emigrated family members in 60 days or be prepared for punishment.

In recent years, reports have grown increasingly common of corrupt Chinese officeholders and their families fleeing the country after amassing huge amounts of money. Many naked officials are believed to have sought shelter in rich countries that do not have extradition treaties with China.

"We have to be more aggressive and active in managing naked officials," Zhao Xiaoqing, a press officer of Beijing Municipal People's Procuratorate, told China Daily on Tuesday.

Zhao said the Central Commission for Discipline Inspection of the Communist Party of China directed the procuratorate and other related authorities to participate in the campaign.

In a recent trial that saw the largest charges of embezzlement ever brought before Beijing courts - involving 580 million yuan ($88 million) - Dong Yuejin, a 'naked' official and former assistant to the general manager of China International Telecommunication Construction Corporation, was convicted of channeling bribe money to his wife overseas.
